OIL-CUP.

Specification of Letters Patent.

lPa't-ented Dec. 2li, 1192i.

To @ZZ whom it may concern.'

Be it known that l, CLAUDE E. Cox, a citizen of the United States, residing at Detroit, in the county of -Wayne and State of lfiiehigan, have invented certain new and useful linprovements in Oil-Cups, of which the following` is a specification.

liy invention relates to improvements in oil cups and has for its object to provide a cup having a novel and advantageous closure-cap.

ln the drawings Figure l is a side elevation showing the oil cup, with its cap in closed position in full lines and in open position in dotted lines; Fig. 2 is a central vertical. section; and Fig. 8 is a plan view with parts broken away.

The oil cup body or base l() may be of any suitable construction7 `generally cylindrical, to provide an oil chamber ll from which a duct l2 leads through the usual threaded attaching-stem, the construction shown being one in which a central stand-pipe 13 connects with said duct and extends nearly to the top of the chamber. This standpipe is shown as surrounded by a slidable sleeve lll normally extendingabove the upper end of the pipe and above the oil level, this sleeve being weighted as at l5 and suspended on a light spring 16 for vertical vibration to feed oil to the central duct as a result of vibration of the cup. l/Vith the details of the functioning of this automatic feed apparatus the present invention is not concerned, save for the facts that it advantageously provides a vertical central duct extending above the normal oil level and open as at 17 at its top, and that it is sometimes desirable to prime the standpipe with oil from al can.

Unto the upper portion of the body is screwed a cover or head 18 formed, above its threaded cylindrical rim 18, into a low or rather long-radius parti-eylindrical dome i9, circular in plan and having one or more apertures therein, these preferably being a central aperture 2O alining with the opening i7 of the stand-pipe for pipe-priming and other apertures 2l between the center and cylinder rim of the dome. Upon the spherical surface of the dome lits a parti-spherical sheet-metal cap 22, substantially conforming in size and shape to the dome and radially pivoted, between the edge of the cap and its center, to the head, as by a double-headed stud 23. rlhe stud is maintained snug in all positions of the cap by a spring washer 2abetween the lower stud-head and the under side of the dome, and the cap preferably has made therein, normally to register with one of the apertures in the dome, a latehingI depression 25. In most instances l prefer to curve the cap on a radius slightly shorter than the radius of the cover-dome (as shown in Fig. 2) so as to accentuate edge-sealing of the cap, lift its center slightly, and give its edge a slight scraping edect when moved over the dome.

Normally the cap stands firmly latched as shown in full lines in Figs. 1 and 2, with its central depression 25 engaging the cen trai hole 20 of the dome, but by applying side-pressure the parti-spherical cap may be swung around on its radially-extending pivot 23, the latching depression 25 springing,` out of its hole 20 against the tension of the cap-instal and of the spring,` washer 24; and, since the sides of the cylinder do not interfere with its mmfeinent7 the cap may be completely or partially rotated upon its pivot at will, thereby exposing one or all of the outer holes 2l and also the central hole 20 if desired. By virtue of its strength due to curvature, its close sealing ofthe margins of the dome and its wiping contact with the dome when moi/ech' this form of a cap is particularly desirable for oilcups subjected to the ravages of fine dust, as those use'd on automobiles, in mill inachinery and the like. Also, it will be noted, the oil cup may be used in very restricted spaces because when fully opened the cap taires up very little lateral space.

l claim l. in oil cup having a parti-spherical dome provided with an oil opening, and a parti-spherical cap pivoted, between its center and edge7to the dome.

2. illn oil cup having a parti-spherical dome, circular in plan7 provided with an oil opening, vand a parti-spherical cap of similar plan area radially pivoted to said cap eccentrically to its circular margin.

3. 5in oil cup having a parti-spherical dome having an opening therethrough, and

through, and a partispherieal cap riveted near one edge to the dome and having a clepression to engage the dome opening.

5. An oil cup comprising a parti-spherioel dome having en opening therethrough, a parti-spherical Cap, a pivot Where-in said cap is 'mounted near its edge to swing over or mainly oil of the dome, and resilient means for Jcensioning Jche pivot.

10 6. The combination with an oil cup body openings.
